Heat & Energy Recovery

American Aldes manufactures Heat and Energy Recovery Ventilators (HRV/ERV) using all available exchange technologies – aluminum, polypropylene, high-latent-transfer enthalpy, polymeric enthalpic membrane, and desiccant wheel – so you can choose the most appropriate method for your application and climate. From small apartments to large commercial buildings, there is an Aldes HRV or ERV that meets your needs. Consult the HRV/ERV Selection Guide for help choosing the appropriate model.

How heat and energy recovery ventilators work
In the heating season, heat recovery ventilators (HRV) and energy recovery ventilators (ERV) draw in fresh air from outside while stale, humid air is exhausted. As the fresh and stale airstreams pass though the unit’s core, the fresh air is tempered with heat recovered from the exhaust air. In the cooling season, fresh outdoor air is cooled by the air-conditioned exhaust air. An ERV will also transfer moisture to improve comfort.
